When out hiking in Hong Kong, I like to have a relevant Hong Kong countryside map on me. For although there are people who seem content to just rely on the many informative signposts and signs erected by the country park authorities, I find that some signposts -- such as the distance posts for such as the four main long trails (i.e., the Hong Kong, Maclehose, Wilson and Lantau Trails) and various official Country Trails -- are more informative when used with a countryside map (which contains markings for them).
More than by the way, for those wondering where the photos above were taking: the top most shot was taken about two thirds into a trek leading from Shek Kong to Ma On Kong; the middle one was taken at the end of Hong Kong Trail Stage 8 (an earlier part of which takes one along the famously scenic Dragon's Back); while the bottom photo is at Sai Kung's Tai Long Wan, where one can rest for a bit before continuing along Stage 1 of the Maclehose Trail.
More re the last photograph: Here's recommending -- like with many other photos I offer up on my Photo Hunt entries (and, actually, my non-Photo Hunt entries too!) -- that you click on it to view an enlarged form of it. For then, you'll not only be able to appreciate the view but also see that one of the informative signs in them say "Warning: Do not cross stream when water covers bridge/stepping stones or the flow is rapid)" while the other contains a graphic illustration featuring what I come to call "the cute little men" of this particular area's big waves and their people tossing strengths! :b
